in reply to Problem in parsing XML file using XMl::Twig

What do you think $$titlename will interpolate as? It will give you the pid of the process + the text 'titlename'.

    Actually it looks like $$titlename will dereference the scalar instead: 
    perl -wle 'use strict; my $bar = 3; my $foo = \$bar; print "$$foo"'
# outputs:  3

    But OP probably doesn't want to use $titlename as a scalar ref .. so the line qq[Title[\@Name="$$titlename"]] => should probably be: 
    qq[Title[\@Name="$$titlename"]] =>

    to OP: use strict; and use warnings; would have caught this saying something like Can't use string ("MyTitleString") as a SCALAR ref while "strict refs" in use at foo.pl line 1234.

      I am sorry! That was a typo created when I copied the code and pasted it in Perl Monks editor. It is one $. And still the problem exists...
      But I realized that I am doing 'new' in a loop and that's why I am loosing the data.
      Can someone suggest me how to correct it?
      Is there a way to create new Xml::Twig and set the handler later?
      Thanks!

        Looking at the POD (i haven't actually tried it) for XML::Twig it looks like you can use the setTwigHandlers ($handlers) method (note there are several set*Handler*() methods).
